Dana Vollmer makes history, brings home more medals for her son

With her son's name Arlen written on her foot, Dana Vollmer dove into Rio De Janeiro's Olympic Aquatics Stadium pool on Sunday and less than a minute later she became the second American woman to win an Olympic swimming medal after having a baby.

Vollmer clinched bronze in the 100 meters butterfly, surrendering her London 2012 title to an impressive Sarah Sjostrom, who clocked a world record of 55.48 seconds.
